In general, minimising a problem with the universal electron-correlation functional is known to in NP due to this [1]. Which is kind of sad for density functional theory (DFT). I've probably misphrased that. Also, side remark: Coding u

Most 'blockchain' proposals I've seen, particularly in civic technology, would be satisfied with a public git repository containing a .csv file, and also generally ignore the social issues around data ownership and quality.

Locating the office in zone 1 also allows people to live in lots of outer London areas. If you site the office in zones 2/3, you have to choose which bit of zones 2/3, potentially meaning people have to move house or commute eve

The mouse is walking along the band, while the end of the band moves away, however the mouse is also being carried along by the expansion of the band. I think the best approach is to think in terms of the fractional coordinate of the mouse

They recently (a few years ago) introduced A* grades for 90+/100 scores, where A was 80/100 before and so, as you note, not very discriminating. I'm not totally sure, but I think a standard offer for one of the elite universi

I agree with your analysis, I did notice that not many groups in the US were doing what looked like interesting new methods/theory, more 'cashing in' on existing code in a fairly short term way. There are people like Louie an

Eh? This isn't my experience of condensed matter DFT at all. It's a pretty hot area in the UK/Europe at least, and there are lots of postdocs being advertised, as well as a reasonable number of new faculty being hired in the

This is a pretty amazing and compelling idea, it feels odd that no one has thought of it before - the article mentions some previous models, what were they?

Particles are sort of mathematically more poorly defined the shorter their lifetime. But yes, a nanosecond is a long time in this context :)

I think it's more that the letter only holds sway in the first place by the implied threat behind it. If the letter is from a bot, there is nothing to back up the threat.

The page keeps mentioning 'isomorphic apps' but I have no idea what those are. From googling, they appear to be JS code that can run client and server-side? Not what I would have guessed!

I think the answer is "with great difficulty". When you're developing something like this, you might have an issue with: - Experiment - Model - Approximation to the model - Numerics - Code (- Compiler & hardware) So, your

During my PhD I found I had to occasionally lock myself in a conference room with a bunch of papers and all the whiteboards to do a sort of "deep dive", in order to get everything into my head and push things forward. Things that

A decade ago? Facebook. I think it's interesting that despite Facebook being vastly uncool, it still fundamentally meets its original need, which is socialising in a university environment.

To be fair, that article is pre-announcement and doesn't have much detail on the actual discovery. Actual paper here: http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116...

Are they going to 10k sized tweets, or some sort of notes facility? It seems like the main use case crying out is people attaching massive blocks of texts as images.

I also worked on a quantum (DFT) code in Fortran 95. I agree on your points, once you get used to it, it's basically isomorphic to C but with better numerical support. Compared to C++ it's verbose but understandable and with littl

Given that Moore's law is about transistor densities, no I don't think quantum computers would qualify. It also seems premature to talk about about a Moore's law equivalent for the cost/density of quantum gates given we

In a way, isn't that just it? They're still 'fighting' over them because they're actually not that important? If they were important, the fight would be over much more quickly.
